Answer 1

is equal to approximately 1.6 kilometers. Therefore, the speed of the race car in kilometers per hour is 99 miles per hour * 1.6 kilometers per mile = 158.4 kilometers per hour.

Explanation:

To convert the speed to kilometers per minute, divide the speed in kilometers per hour by the number of minutes in an hour. There are 60 minutes in an hour, so the speed in kilometers per minute is 158.4 kilometers per hour / 60 minutes per hour = 2.64 kilometers per minute.
